Elderly persons with dementia are at risk for seizures, however, traditional anticonvulsants are poorly tolerated in this population. Our goal is to examine Levetiracetam (Keppra) in elderly dementia patients with seizures. While it has been established that Keppra controls seizures in this age group, it is important to demonstrate that treatment with Keppra would not affect cognitive abilities in this large population of patients . As this population is already cognitively impaired, the best choice of anticonvulsant would be one that does not further compromise their cognitive abilities. Keppra is an excellent anticonvulsant agent in the elderly for a variety of reasons, including safety, favorable side effect profile, lack of interaction with other drugs, and efficacy. Our retrospective pilot data suggests that cognition is not negatively affected by Keppra. The current prospective study will assess the cognitive abilities of persons with cognitive impairment at baseline and at weeks 4 and 12. The overall objective is to determine the cognitive tolerability of Keppra for seizures in elderly cognitively impaired patients.
